The surface laminating operation of geomembrane is the most important step in the production of geomembrane;

[0003] In the existing technology, during the geomembrane laminating process, the staff needs to first adjust the thickness of the film of the laminating machine. At this time, the staff needs to hold a hexagonal wrench to adjust the bolts on the die head of the laminating machine one by one. Due to the large number of bolts that need to be adjusted, a lot of energy is consumed in the adjustment process. Manual adjustment by the staff is likely to cause differences between the screws, resulting in uneven thickness of the subsequent laminating. Secondly, before laminating, the solidified waste at the die outlet needs to be cleaned. At this time, the staff needs to remove the internal blockages on both sides of the die, and then use a brass scraper to scrape and clean it. The operation is very cumbersome, which greatly reduces the efficiency of production and processing.

[0027] See also Figure 1-Figure 9 The present invention provides a technical solution: a geomembrane laminating device for recycling and reusing waste materials, comprising a laminating machine 1 and a die head 2. A mounting base plate 3 is fixedly mounted on the side wall of the die head 2. A plurality of mounting blocks 4 corresponding to the bolts are fixedly mounted on the bottom end of the mounting base plate 3. A rotating cylinder 5 is rotatably connected to the inner side of the mounting block 4. A hexagonal plug 6 is fixedly mounted on the end of the rotating cylinder 5 close to the die head 2. The ends of the hexagonal plug 6 are inserted into the inner side of the adjacent bolts. An adjusting mechanism is arranged on the side wall of the mounting base plate 3. The adjusting mechanism is used to control the synchronous rotation of a plurality of hexagonal plugs 6 and can meet the adjustment of a single bolt. Two L-shaped scraping strips 7 are arranged at the bottom opening of the die head 2. An opening and closing mechanism is arranged at the right end of the right L-shaped scraping strip 7. The opening and closing mechanism is used to adjust the distance between the two L-shaped scraping strips 7 according to the degree of overall rotation of the bolt.

[0028] The adjusting mechanism includes a plurality of rotating shafts 8 corresponding to the rotating cylinder 5 and rotatably connected to the right end of the mounting base plate 3. The plurality of rotating shafts 8 are connected by a first transmission belt 9. A transmission gear 10 is fixedly installed on the right end of the rotating shaft 8. A gear ring 11 is arranged on the outer side of the rotating cylinder 5. The gear ring 11 meshes with the transmission gear 10. A slide groove 12 is provided at the top of the rotating cylinder 5. An L-shaped block 13 is slidably connected to the inner side of the slide groove 12 through a compression spring. The top of the L-shaped block 13 is fixedly connected to the inner wall of the gear ring 11. A hexagonal slot 14 is provided at the right end of the rotating cylinder 5. The left side of the hexagonal slot 14 is connected to the slide groove 12. The right end of the L-shaped block 13 is inserted into the inner side of the hexagonal slot 14. A rotating mechanism is provided at the front end of the die head 2. The rotating mechanism is used to drive the transmission gear 10 at the front end to rotate.

[0029] During operation, when the coating thickness of the die head 2 needs to be adjusted, the staff only needs to drive the transmission gear 10 at the front end through the rotating mechanism. The transmission gear 10 at the front end rotates through the first transmission belt 9 to drive the multiple transmission gears 10 to rotate synchronously. The transmission gear 10 rotates to drive the gear ring 11 to rotate. The gear ring 11 rotates through the L-shaped block 13 and the slide groove 12 to drive the rotating cylinder 5 to rotate on the inner side of the mounting block 4. The rotating cylinder 5 rotates through the hexagonal plug block 6 to drive the bolts to rotate, thereby achieving the adjustment of a group of bolts at the same time, so that the staff no longer needs to use a wrench to twist and adjust one by one, which greatly reduces the workload of the staff and brings convenience to the adjustment operation of the die head 2; through the synchronous rotation of the bolts, it is ensured that the rotation degree of each bolt is the same, so that the adjustment is more accurate and the occurrence of missed adjustment and different adjustment degrees is avoided;

[0030] When one of the bolts needs to be adjusted separately, it is only necessary to insert the hexagonal wrench into the hexagonal slot 14. During the insertion process, the hexagonal wrench pushes the L-shaped block 13 to move left, and the L-shaped block 13 moves leftward, pushing the gear ring 11 connected thereto to move leftward until the hexagonal wrench can no longer be inserted. At this time, the gear ring 11 and the adjacent transmission gear 10 are no longer engaged with each other, so that when the hexagonal wrench is turned, it will not affect the remaining bolts, thereby increasing the applicability of the device, bringing convenience to the staff's adjustment work of the die head 2, and solving the problem that the existing waste recycling and reuse geomembrane laminating device does not have a convenient adjustment function for the die head 2 bolts.

[0031] As a further solution of the present invention, the rotating mechanism includes a rotating rod 15 rotatably connected to the right side of the front end of the die head 2, a disc gear 16 is fixedly installed on the right end of the rotating rod 15, a hand-held rotating rod 17 is rotatably connected to the right end surface of the disc gear 16, and a locking mechanism is provided at the left end of the disc gear 16, and the locking mechanism is used to lock the disc gear 16;

[0032] During operation, the disc gear 16 is unlocked through the locking mechanism, and then the handheld rotating rod 17 is held to rotate the disc gear 16. The rotation of the disc gear 16 drives the transmission gear 10 at the front end to rotate, thereby providing power for the rotation of the transmission gear 10. Since the size of the disc gear 16 is much larger than that of the transmission gear 10, the staff can rotate the disc gear 16 more easily, which further facilitates the use of the device and increases the practicality of the device.

[0033] As a further solution of the present invention, the locking mechanism includes a limit ring 18 fixedly installed on the right side of the front end of the die head 2, an L-shaped push rod 19 is slidably connected to the inner side of the limit ring 18, a plurality of locking grooves 20 in a ring array are opened on the outer side of the rotating rod 15, and the bottom end of the L-shaped push rod 19 passes through the locking groove 20 at the top end and is slidably connected thereto;

[0034] During operation, it is only necessary to pull the horizontal end of the L-shaped push rod 19 upwards until the bottom end of the L-shaped push rod 19 moves out from the inner side of the locking groove 20, thereby unlocking the rotating rod 15; by setting up the locking mechanism, the disc gear 16 is prevented from being accidentally rotated, thereby ensuring the stable operation of the laminating machine 1.

[0035] As a further solution of the present invention, the opening and closing mechanism includes a limit rod 21 fixedly installed on the right side of the bottom end of the die head 2, a trapezoidal block 22 is slidably connected to the outer side of the limit rod 21, the left side of the bottom end of the trapezoidal block 22 is fixedly connected to the L-shaped scraper 7 on the right side, a slide rod 23 is fixedly installed on the bottom end of the left L-shaped scraper 7, the right end of the slide rod 23 passes through the trapezoidal block 22 and is slidably connected thereto, a push-pull mechanism is provided at the right end of the trapezoidal block 22, and the push-pull mechanism is used to push the left L-shaped scraper 7 to move left and right through the slide rod 23 when a plurality of hexagonal plug blocks 6 rotate synchronously, and a push-pull handle 24 is fixedly installed on the right side of the top end of the trapezoidal block 22;

[0036] When working, the adjusting mechanism starts to adjust the bolt. During the adjustment process, the hexagonal plug 6 rotates and pushes the slide bar 23 to slide in the water through the push-pull mechanism. The horizontal movement of the slide bar 23 drives the left L-shaped scraper 7 to move horizontally. Taking the adjustment mechanism to adjust the coating thickness to be thinner as an example, the opening at the bottom end of the die head 2 gradually becomes narrower. At the same time, the push-pull mechanism drives the left L-shaped scraper 7 to gradually approach the right L-shaped scraper 7 through the slide bar 23, thereby realizing the adjustment of the position of the L-shaped scraper 7 according to the width adjustment degree of the bottom end opening of the die head 2, ensuring that the L-shaped scraper 7 is always tightly fitted with the inner wall of the opening of the die head 2, and will not hinder the adjustment of the die head 2, greatly increasing the applicability of the device; when it is necessary to clean the waste at the opening of the die head 2, the staff only needs to pull the push-pull handle 24 back and forth, which greatly shortens the cleaning steps, further improves the efficiency of production and processing, brings convenience to the cleaning of the die head 2, and solves the problem that the existing geomembrane coating device for waste recycling and reuse does not have a convenient cleaning function at the discharge port of the die head 2.

[0037] As a further solution of the present invention, the cross section of the vertical end of the L-shaped scraper strip 7 is triangular, and the two right-angled sides of the L-shaped scraper strip 7 are in contact with the bottom end of the die head 2 and the inner wall of the opening;

[0038] During operation, the vertical end of the L-shaped scraper strip 7 slides inside the die head 2, and the inclined surface of the L-shaped scraper strip 7 can better scrape off the adhered waste, making it easier for the staff to push and pull the equipment for cleaning.

[0039] As a further solution of the present invention, the push-pull mechanism includes a limit box 25 fixedly installed at both the front and rear ends of the right side of the die head 2, a lifting rod 26 is arranged between the two limit boxes 25, the front and rear ends of the lifting rod 26 respectively pass through the two limit boxes 25 and are slidably connected thereto, a push-pull rod 27 is slidably connected to the outer side of the lifting rod 26, a hinged rod 28 is hinged at the bottom end of the push-pull rod 27, the other end of the hinged rod 28 is hingedly connected to the right end of the slide bar 23, the inner side of the limit box 25 is rotatably connected to a threaded rod 29, the bottom end of the threaded rod 29 passes through the lifting rod 26 and is threadedly connected thereto, and a transmission mechanism is arranged at the top of the limit box 25, and the transmission mechanism is used to drive the threaded rod 29 to rotate synchronously when the hexagonal plug 6 rotates synchronously as a whole;

[0040] During operation, the transmission mechanism starts to drive the two threaded rods 29 to rotate synchronously. The rotation of the threaded rods 29 drives the lifting rod 26 to move horizontally up and down through the action of the threads. Taking the upward movement of the lifting rod 26 as an example, the upward movement of the lifting rod 26 drives the push-pull rod 27 to move upward, and the upward movement of the push-pull rod 27 drives the top end of the hinged rod 28 to move upward. The top end of the hinged rod 28 moves upward so that its other end pulls the slide rod 23 to slide to the right, thereby providing power for the horizontal movement of the slide rod 23, wherein the moving distance of the slide rod 23 is proportional to the number of rotations of the threaded rod 29.

[0041] As a further solution of the present invention, the transmission mechanism includes a first transmission rod 30 and a second transmission rod 31 which are rotatably connected on the right sides of the front and rear ends of the die head 2, the first transmission rod 30 is located at the lower side of the second transmission rod 31, the top end of the threaded rod 29 passes through the top end of the limit box 25 and is connected to the first transmission rod 30 through a bevel gear 32, the right end of the first transmission rod 30 is connected to the second transmission rod 31 through a second transmission belt 33, and the right end of the second transmission rod 31 is connected to the adjacent rotating shaft 8 through a third transmission belt 34;

[0042] During operation, the rotating mechanism drives the transmission gear 10 and the rotating shaft 8 to rotate. The two rotating shafts 8 at the front and rear ends drive the second transmission rod 31 to rotate through the third transmission belt 34. The second transmission rod 31 rotates through the second transmission belt 33 to drive the first transmission rod 30 to rotate. The first transmission rod 30 rotates through the bevel gear 32 to drive the threaded rod 29 to rotate, thereby providing power for the rotation of the threaded rod 29. The number of rotations of the threaded rod 29 is proportional to the number of rotations of the transmission gear 10, so that the moving distance of the left L-shaped scraper 7 is proportional to the number of rotation adjustment circles of the bolt.
